I use this because I am bipolar type 2. I take 4 per day and it helps a lot with hypomania. If I forget to take these for a couple days, I get hypomanic again & I feel like I'm almost going insane, but then when I take them again, it goes away. Also, I'm really not a morning person AT ALL and they also help with morning grogginess. I still hate waking up early for work but I don't have that yucky tired feeling in my brain as much when I take these on a daily basis. The only cons are that 1. the pills are really big so I have to drain the oil out, add some lemon juice & water, and gulp it. and 2. they taste fishy. I find that when I drink the oil/lemon mix on an empty stomach, wait about a half hour & then eat something, I don't get a nasty fishy burp.
